Many settlers from the southern United States moved to Texas in the 1820s. What caused this move? A battles between Spain and the U.S. on the east coast of North America B high taxes on settlers in Mexico by the Mexican government C. new colonization laws and land offerings from the Mexican government (D) Texans losing the Battle of the Alamo to General Santa Anna

To determine the cause of the movement of settlers from the southern United States to Texas in the 1820s, let's analyze each option: A. **Battles between Spain and the U.S. on the east coast of North America**: This option is not directly related to the migration to Texas, as the battles mentioned occurred in a different region and context. B. **High taxes on settlers in Mexico by the Mexican government**: While taxes can influence migration, this option does not accurately reflect the primary reasons for the influx of settlers to Texas during this period. C. **New colonization laws and land offerings from the Mexican government**: This option is historically accurate. In the 1820s, the Mexican government encouraged settlement in Texas by offering land grants and favorable colonization laws, which attracted many settlers from the southern United States. D. **Texans losing the Battle of the Alamo to General Santa Anna**: This event occurred later, in 1836, and was a result of tensions that had already developed. It did not cause the initial migration in the 1820s. Based on this analysis, the correct answer is: **C. new colonization laws and land offerings from the Mexican government.**
